In the figure: the device comprises a rotary table 1, an annular boss 3, an annular electromagnet 4, a tool apron 5, a cutter 6, a proximity switch 7, a connector 8, a rotating shaft 9, a chuck 11, a matching block 12, a guide inclined plane 13, a push rod 14 and a connecting plate 15.

Detailed Description

The utility model is explained in further detail below with reference to the figures and the detailed description:

example (b):

referring to fig. 1 to 4, a machining center tool magazine switching device includes a turntable 1, a rotating machine for rotating the turntable 1, a plurality of jacks located at the edge of the turntable 1, an annular boss 3 located on the inner wall of the upper end of the jack, an annular electromagnet 4 located on the lower side of the annular boss 3, a tool apron 5 located in the jack, a tool 6 located on the lower side of the tool apron 5, a proximity switch 7 located on the inner wall of the jack and used for sensing the tool apron 5, a connector 8 located on the upper side of the tool apron 5, a rotating shaft 9 located above one of the jacks, a connecting mechanism located at the lower end of the rotating shaft 9 and used for being matched with the connector 8, a motor used for rotating the rotating shaft 9, and a lifting device used for lifting the motor;

the annular electromagnet 4 is used for adsorbing the tool holder 5.

The connector 8 comprises a connecting plate 15 fixedly connected to the upper end of the tool apron 5 and clamping heads 11 fixedly connected to two opposite sides of the connecting plate 15;

the connecting mechanism comprises a slot which is positioned at the lower end of the rotating shaft 9 and used for inserting the connector 8, side grooves which are positioned at two opposite sides of the slot, a matching block 12 which is connected in the side grooves in a sliding manner and used for matching with the chuck 11, a return spring which is positioned in the side grooves and used for returning the matching block 12, a guide inclined plane 13 which is positioned at one side of the matching block 12, a push rod 14 which is connected in the rotating shaft 9 in a sliding manner and used for extruding the guide inclined plane 13 so as to enable the matching block 12 to be far away from the slot, and an electric cylinder which is positioned in the rotating shaft 9 and used for driving the push rod 14;
